The building is owned by the San Francisco-based Internet Archive, which operates a giant repository of public domain media and the widely-used Wayback Machine, which preserves over 340 billion copies of websites dating back to the mid-1990s.

The Internet Archive tweeted Wednesday morning that the building housed a “scanning center” used by the website. The library’s main building and data are reported to be safe.

A spokesperson for the website said “unscheduled interruptions” to Internet Archive services were possible throughout the day as a result of the fire.
